From That Point The River Decreased In Size With
Every Branch Creek That Joined It, And Now It Had Decreased To
Nothing.
No high ranges form its head.
The hills forming its
water-shed become gradually lower as we approach its termination, or
rather beginning, at the desert's edge. The desert's edge is a raised
plateau of over 2000 feet above the sea-level - the boiling point of
water being 208 degrees = 2049 feet - and being about 350 miles in a
straight line from where the Ashburton debouches into the sea. My camp
upon the evening of the 29th of May, a little westward of the
bluff-faced hill before mentioned, was in latitude 24 degrees 25' and
longitude 119 degrees 58'. We remained here during the 30th. The
horizon to the east was formed by a mass of low ranges; from them we
saw that several diminutive watercourses ran into our exhausted
channel. I could not expect that any hills would extend much farther
to the east, or that I should now obtain any water much farther in
that direction. A line of low ridges ran all round the eastern
horizon, and another bluff-faced hill lay at the south-west end of
them. The whole region had a most barren and wretched appearance, and
there was little or no vegetation of any kind that the camels cared to
eat. Feeling certain that I should now almost immediately enter the
desert, as the explorer can scent it from afar, I had all our
water-vessels filled, as fortunately there was sufficient water for
the purpose, so that when we leave this camp we shall not be entirely
unprepared.
The morning of the 31st of May was again cold, the thermometer falling
to 27 degrees, and we had a sharp frost. I was truly delighted to
welcome this long-expected change, and hoped the winter or cool season
had set in at last. This day we travelled east, and went over low,
rough ridges and stony spinifex hills for several miles. At about
eleven miles, finding a dry water-channel, which, however, had some
good camel shrubs upon its banks, we encamped in latitude 24 degrees
28', being still among low ridges, where no definite view could be
obtained. On June the 1st we travelled nearly east-north-east towards
another low ridge. The ground became entirely covered with spinifex,
and I thought we had entered the desert in good earnest; but at about
six miles we came upon a piece of better country with real grass,
being much more agreeable to look at. Going on a short distance we
came upon a dry water-channel, at which we found a deep native well
with bitter water in it. We encamped in latitude 24 degrees 24'. The
night and following morning were exceedingly cold - the thermometer
fell to 18 degrees.
We had not yet reached the low ridge, but arrived at it in two miles
on the morning of the 2nd. From it another low ridge bore 23 degrees
north of east, and I decided to travel thither.
To-day we had a good deal of country covered with ironstone gravel; we
passed a few grassy patches with, here and there, some salt bush and
acacia flats; there were also many desert shrubs and narrow thickets.
The camp was fixed nearly under the brow of the ridge we had steered
for, and it was quite evident, though a few ridges yet appeared for a
short distance farther east, that we had at length reached the
desert's edge and the commencement of the watershed of the western
coast. It will be observed that in my journey through the scrubs to
Perth, I had met with no creeks or water-sheds at all, until after I
reached the first outlying settlement.
The question which now arose was, what kind of country existed between
us and my farthest watered point in 1874 at the Rawlinson Range? In a
perfectly straight line it would be 450 miles. The latitude of this
camp was 24 degrees 16' 6". I called it the Red Ridge camp. Since my
last attack of ophthalmia, I suffer great pain and confusion when
using the sextant. The attack I have mentioned in this journey was by
no means the only one I have had on my numerous journeys; I have
indeed had more or less virulent attacks for the last twenty years,
and I believe the disease is now chronic, though suppressed. From the
Red Ridge camp we went about eight miles east-north-east, and I found
under a mass of low scrubby hills or rises tipped with red sandstone,
a rocky cleft in the ground, round about which were numerous old
native encampments; I could see water under a rock; the cleft was
narrow, and slanted obliquely downwards; it was not wide enough to
admit a bucket. There was amply sufficient water for all my camels,
but it was very tedious work to get enough out with a quart pot; the
rock was sandstone. There was now no doubt in my mind, that all beyond
this point was pure and unrelieved desert, for we were surrounded by
spinifex, and the first waves of the dreaded sandhills were in view.
The country was entirely open, and only a sandy undulation to the
eastward bounded the horizon. The desert had to be crossed, or at
least attempted, even if it had been 1000 miles in extent; I therefore
wasted no time in plunging into it, not delaying to encamp at this
last rocky reservoir. After watering our camels we made our way for
about four miles amongst the sandhills. As we passed by, I noticed a
solitary desert oak-tree, Casuarina decaisneana, and a number of the
Australian grass-trees, Xanthorrhoea. The country was almost destitute
of timber, except that upon the tops of the parallel lines of red
sandhills, which mostly ran in a north-east and south-west direction,
a few stunted specimens of the eucalypt, known as blood-wood or red
gum existed.
